Chemical and pharmacological properties of subtilisins

Author Affiliations

Abstract

Subtilisins are a class of hydrolases proteolytic enzymes produced by the bacteria Bacillus subtilis. The study of the chemical and pharmacological properties of subtilisin has been actively conducted the last 20 years. The interest has been caused by the presence of subtilisin fibrinolytic, thrombolytic and anticoagulation action. In this case, separated subtilisins show different fibrinolytic activity, and some of them are even more active than urokinase. Subtilisins effect does not have site-specificity and is directed to those proteins that have lost native globular structure (e.g., fibrinogen, into fibrin turned). It is known that the population of Japan, China and North East India are characterized by the lowest risk of heart diseases and dementia, perhaps this is due to the high content of fibrinolytic enzymes in traditional food (nattokinase from soybeans). Despite the large number of experimental studies, the subtilisins practical use in medicine remains limited. The only registered drug for thrombosis treatment is Russian medicine Trombovazim® created in 2009 and based on immobilized subtilisin.
